Discover 6 Ways That Attic Air Sealing Makes a Difference

Your ceiling’s primary purpose is to serve as a barricade that keeps the outside air that resides in the attic from entering into your home’s living space. There are points along this barricade where openings exist, and air leakage takes place. These points are also known as bypass areas. Each bypass area reduces the energy efficiency of your home. You can prevent this from happening by taking the time to seal your attic space. Discover the six ways that attic air sealing makes a difference.

 

1. Insulation is More Effective

 

Insulation is an essential ingredient to maintaining a level of warmth in your home during the winter and keeping things cool during the summer months. It does not, however, prevent air from moving through it and coming into your home. Air movement through the insulation works to reduce the benefit the insulation should provide.

 

Schedule an Audit

 

One way to know if there are bypass areas in your insulation is to have a home energy audit or commercial energy audit done. This procedure increases the health and safety of the occupants in your home or building while increasing the comfort level and structural durability of the building as well. Air sealing your attic space also works to reduce the flow of air through the insulation. It places a protective shield around the insulation and prevents bypass areas from forming.

 

2. Reduces the ‘Stack Effect’

 

The stack effect is the process of warmer indoor air rising to the ceiling and continuing into the attic through the bypass areas, cracks and other crevices that are present. Areas around recessed lighting fixtures, drop-down attic stairs and wall cavities where electrical wiring and plumbing lines run are also places where warm air escapes into the attic.

 

How the Stacking Effect Happens

 

As the warm air moves into the attic space, colder outside air gets pushed into your living space creating a cooler temperature for the home. Your house has the presence of a stack effect when you feel a draft near an exterior wall or window space. Your basement space may be colder as well. Having warm air escape your home and cold air come in requires your heating unit to work twice as hard to heat your living space. This produces higher electricity bills in the winter months. Air sealing your attic prevents the stack effect from taking place.

 

3. Prevents Moisture From Forming

 

When there are bypass areas, cracks, crevices or openings of any kind that allows air to pass between your living space and the attic, it opens the door for moisture entering into the attic as well. Each time you shower, cook or do laundry, moisture enters into the air and travels up to the attic.

 

What Happens Where Moisture Lingers

 

Once there, the moisture condenses and turns into areas of mold or mildew in your attic. When left unattended, the mold and mildew causes damage to the wood beams in your attic and causes toxic air to leak into your home. This may cause long-term health issues for you and other residents in your home. By air sealing your attic, you are preventing moisture from reaching the attic and forming harmful deposits of mold or mildew.

 

4. Keeps Attic Air Out of Living Space

 

The air that resides in your attic space can contain toxins and other harmful ingredients that come from asbestos, mold or mildew, and fiberglass particles. Your attic may also have the presences of cracks and small openings that allow the air from your attic to enter into the living space of your home.

 

Breathing in Toxins

 

This makes it possible for the toxins and other harmful particles to become something you breathe in on a regular basis. You and others residing in your home may experience health issues as a result. To prevent the attic air from mixing with your living space’s air, you need to seal your attic.

 

5. Decreases Drafts in the Home

 

Any unnatural flow of air from your attic into your living space will create a draft. Air drafts also happen in recessed lighting fixture spaces, the opening around an overhead attic door and the spaces between the walls were electrical and plumbing systems run.

 

How Air Sealing Makes a Difference

 

An air sealing project in your attic works to seal off any open stud cavities, gaps behind a knee wall and any other major gaps of space that are present. It will reduce the presence of drafts, which may currently be impacting your gas and electrical bills each month.

 

6. Improves Home Energy Efficiency

 

Each gap, crevice or crack in your attic allows air to escape into your home. It also allows warmer, healthier air from your living space to escape into the attic.

 

Keep Heat Where It Belongs

 

During the winter months, your heater will be unable to keep up with heating the air inside your home since there will always be the existence of cooler air. Air sealing your attic creates a barrier inside your attic that keeps the cold air where it belongs. As a result, you will see lower electric bills and have a more energy efficient home.

 

During a home energy audit, property owners will find out where air sealing should be done and other cost-effective ways to improve energy efficiency and reduce their utility bills.
